Lowri Turner , Nick Knowles and the team take on one of the biggest challenges ever undertaken on the show - fixing a lethal staircase. Plus, a bedroom that was once a bathroom, dangerous masonry and awkward bathroom noises.

While Nick Knowles and the team transform a garage extension in Surrey into a children's playroom, Lowri Turner finds out about the mother who took a hammer to her hallway, the wife who wants action on her bathroom rennovation and the man who axed his bannisters.
